It's well known that [1]}, [2]}, [3]} under dimensional regularization, an one-loop scattering amplitude or a general one-loop Feynman integral in \(D=d_0-2\epsilon \) -dimensional spacetime can be rewritten as a linear combination of some scalar master integrals (MIs) as
\(I=\sum _{i_{d_0+1}} C_{d_0+1}^{i_{d_0+1}} I_{d_0+1}^{i_{d_0+1}}+\sum _{i_{d_0}} C_{d_0}^{i_{d_0}} I_{d_0}^{i_{d_0}}+\cdots + \sum _{i_1} C_1^{i_1} I_1^{i_1}, \)
